a The number of bear sightings reported each year is dependent upon park visitation, observer effort, the number of on-going bear related research projects, availability of preferred bear foods, weather patterns, and other factors. The system was not designed to provide unduplicated samples of bear numbers. The number of bear sightings reported is not considered to be an indicator of population numbers or trends.

b In 1993, the bear sighting reporting system was entered into a computer data base allowing computer tallying of the data. Bear sighting summaries from previous years were hand tallied and therefore may differ from these updated numbers.

c Multiple bears observed together such as females with cubs or mating pairs are recorded as one bear sighting report. Multiple reports obviously representing the same bear on the same day were also recorded as one sighting.

d Sign includes tracks, scats, feeding sights, day beds, and den sites.
